MACHINE FOR MAKING TACK-STRIPS.

SPECIFICATION forming part of Letters Patent No. 402,062, dated April23, 1889. Application filed December 18, I888. Serial No. 293,844. (Nomodel.)

To all whom it may concern.-

Be it known that I, MATTHIAS BROOK, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in Machines for MakingTack-Strips, of which the following description, in connection with theaccompanying drawings, is a specification,

. like letters on the drawings representing like This invention isintended as'an improvement upon the class of machine represented inapplication Serial No. 293,943, filed 18th day of December, 1888. Themachine described in the application referred to contains a fingerhaving a projection and an inclined face, the said finger beingconnected with a slide or equivalent devlce by which to reciprocate it,so that when a tack is present in the strip the tack by its contact withthe finger will cause a projection thereon to engage and move aratchet-wheel. The finger described in the saidapplication has ashoulder which acts directly 'upon a driven tack, and by pressureagainst the tack in the strip moves the strip through the machine.

In my present invention I employ a finger mounted upon a slide, thefinger having a projection and also an inclined face, as represented inthe said application; but instead of the shoulder to strike the body ofthe tack and feed the strip I have provided the machine with aprojection, which is controlled by or through the movement of the fingerto effect the movement of the strip-feeding mechanism, the saidprojection, as shown, engaging or moving a pawl-carrier having a pawl,which in turn engages a ratchet-wheel which imparts motion to thestrip-feeding mechanism. (Shown as a wheel.)

In my improvement, when the inclined part of the finger acts against atack properly driven into the strip, the finger, by its movement inconnection with the device referred to, effects a movement of the feedmechanism or wheel; but in case a tack is not properly driven into thestrip then the finger referred to is not actuated, and the feedingmechanism referred to, which acts directly upon the strip, is not moved.

My invention in tack strip making machines consists, essentially, in afeeding mechanism to engage and feed a tack-strip, a guideway for thetacks, a driver to drive the tacks,

and a roadway for the tacks driven into the strip, combined with a slideand a finger thereon having a beveled face and a projection, whereby thefinger moved by a tack as the slide is moved toward a driven tack ismade to effect the movement of the feeding mechanism to feed the strip,substantially as will be described.

Figure 1 in elevation shows a sufiicient portion of a tack-strip-makingmachine embodying my invention to enable the same to be understood. Fig.2 is a top or plan View of Fig. 1. Fig. 3 is a right-hand end View ofthe parts shown in Fig. 1. Fig. 4 shows the finger detached. Fig. 5shows the pawl-carrier and pawl for actuating the feeding mechanismwhich operates directly upon the strip. Fig. 6 is a detail showing amodification, and Fig. 7 is a top View of Fig. 6. Fig. 8 is a sectionaldetail chiefly to show the sleeve a Fig. 9, a detail of the rockinglever 17; Fig. 10, details showing the lever b in two differentpositions, and Fig. 11 two different views of the lever (1 Referring tothe drawings, the driver 0 and the driveway or throat having adriver-passage therein through which the tack passes as it is beingdriven by the driver into the paper or other strip, the arm al theroadway E in which travel the shanks or bodies of the tacks after theyhave been driven into the usual paperor other strip, the frame-work A,the groove 2 in the roadway E the slide a therein, the ratchet-wheel 0,the sleeve a to which it is attached, the beveled gear a, the pinion aengaged by it and mounted loosely on the stud 6, the bolt a theshoulderplate 13 loose on the stud 6, the disk I), it forming part of aspacing mechanism and having a notch, 8, and the cam-plate c, the

enlargement E of the roadway E the sliding 5 upon the headed stud 18,the studs 22 23, extended from the lever (1 the said stud 22 entering atransverse slot in the carriage d, and the stud 23 entering the cam-slot2d of a lever, 25, pivoted at 26 and having a pawl, 26*, attachedthereto by a knuckle-joint of any usual construction, the frame-work e,having a suitable guideway in which slides a presser-foot, 6, having ablock, e the means to move it and the said presser-foot e, the lever f,the link f, connected to the carriage e at 20, and the means operated bythe said lever f and the arm 9 and the cutting mechanism g are and maybe all as fully described in the application referred to, wherein thesame letters are employed to designate like parts; so the constructionand specific operation of the said devices need not be herein furtherspecifically described.

Herein it will be noticed that the slide a has pivoted upon it at h afinger, h, having a beveled side, 4, and a projection, 5. The projection5 engages and operates the ratchetwheel a whenever the inclined side 4of the finger comes in contact with a tack which has been properlydriven. The finger h (see Figs. 1 to 5) is so mounted and constructed asto move in unison with it a projection, 7L and cause it to engage aprojection, m, on and reciprocate a pawl-carrier, m, herein shown as aslide and provided with a pawl, m the said pawl-carrier being hereinrepresented as of dovetailed shape in cross-section, (see Fig. 3,) andfitted to slide in a dovetailed guideway in an upright frame or stand,B, constituting a part of the frame-work of the machine.

The stand B, as herein represented, has two stud-screws, B B whichreceive upon them two wheels, B B between which passes the strip ofpaper into which are to be driven the tacks to constitute thetack-strip, the said paper being taken from a suitable reel or source ofsupply. The wheel B has attached to or forming part of it aratchet-wheel, B, which is engaged and rotated intermittently by thepawl m mounted upon the pawl-carrier m. The pawl-carrier has aprojecting pin, 60, (see Fig. 1,) which is engaged by a spring, 61,having one end secured to the stand B, the said spring acting to movethe pawl-carrier backward as the slide a is retracted or moved to theright. The pawl is normally pressed toward the ratchet-wheel B by asuitable spring.

Instead of the pawl-carrier and pawl for moving the feed mechanismdescribed for the strip, I may employ any other equivalent mechanismcommonly employed for rotating a feed-wheel in a sewing or othermachine.

It will be noticed that the feeding mechananism herein described actsdirectly upon the strip into which the tacks are to be driven, and thatthe said feeding mechanism is not actuated to feed the strip except whenatack has been properly driven into the same.

I do not desire to limit my invention to the exact shape of that part ofthe finger having the projection 7L4, whereby the movement of the fingerderived by coming in contact with a driven tack is made to actuate thefeeding mechanism.

In the application referred to I have shown the finger itself asprovided with a toe which enters a notch in the strip itself.

In Figs. 6 and 7, showing a modification of my invention, I haverepresented the finger h as prolonged, and the projection h at its innerend is made to engage side ratchet-teeth of a ratchet-wheeLB", (shown asa ring secured to the feed-wheel B the engagement of the projection hwith the teeth of the ratchet-wheel being determined by the action ofthe beveled end 4 of the forwardly-moving finger against a tackpreviously driven into the strip. The engagement of the projection hwith the feed-wheel continues so long as the finger acts against thetack; but when the slide a is retracted the projection 5, by slippingback over the teeth of the ratchet-wheel, causes the projection h to bedisengaged from the teeth of the ratchet-wheel.

I claim- In a tack-strip-making machine, feeding mechanism to engage andfeed the tack-strip, a guideway for the tacks, a driver to drive thetacks, and a roadway for the tacks driven into the strip, combined witha slide and a finger therein having a beveled face and a projection,whereby the finger moved by a tack, as the slide is moved toward adriven tack, is made to effect the movement of the feeding mechanism tofeed the strip, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MATTI'IIAS BROOK.
